To all whom, it may concern-.-

Be it known that I, RILEY J. HOSNER, of Romeo, county of Macomb, State of Michigan, have invented a new and useful Improve ment in Stone Lifters and Carriers; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form apart of this specification.

My invention consists of the combinations of devices and appliances hereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a rear elevation of a device embodying my invention. Fig. 2 is a side elevation of the same.

My invention relates to a novel device for lifting and carrying stones, and is designed especially for clearing a field of heavy stones.

The following is a description of my invention, reference being had to the accompanying drawings, in which A represents one side of a frame, and A a corresponding side, the two united by suitable strengthening-braces, a, and cross-bars a. These side timbers of the frame A A are preferably constructed each of a single bent piece, the two extremities engaged with the front bolster and rear axle, B and B, respectively, the engagement being effected in any suitable manner. The timbers are bent upward toward the center, to give a suitable height to the frame at that point, midway of the front and rear wheels, 0 and O, mounted on their respective axles. The timbers A and A are so constructed and arranged, preferably, so as to approach each other intermediate of their ends, as shown in Fig. 1. Midway the ends of said timbers I locate a metallic saddle, D, uniting said timbers and forming the bearings of a laterally-extended shaft, E. e and 6 denote the journal-boxes of said shaft. Located upon said shaft is a sprocket-wheel, F, a brake-drum, G, and ratchet-wheel H. These may be made separate or integral, as may be preferred. I is a chain, engaged at one end with the frame and passed over said sprocket-wheel. The opposite end may hang free. J is a sheave sup ported upon said chain, and supporting in turn a gripping device, K, of any desired construotionas, for instance, of similar form to a pair of ice-tongsadapted to grip and raise a stone as the chain is shortened by the rotation of the sprocket-wheel. L represents a pawl adapted to engage the ratchet-wheel H, and provided with an extended arm, h, engaged with a lever, M, preferably bent at its inner end, as shown in Fig.2, and pivotally engaged with the rear of the frame or with the rear bolster. By engaging the arm h with the lever, as shown, it is evident that when the lever is thrown upward the pawl L is projected forward and disengaged from the ratchet-wheel, and, vice versa, when the lever is forced downward the pawl engages with the ratchet-wheel and gives it a partial rotation, and thereby also partially rotating the sprocket-wheel mounted on the same shaft as the ratchet-wl1eel. It is in this manner that power is applied to raise the stones S. To hold every advantage gained, I also provide an additional pawl, N, constructed to drop behind the successive teeth of the ratchet-wheel and effectually prevent any backward rotation until it is desired to lower the stone. This pawl N is pivotally engaged upon the saddle D.

P is a band-brake, encircling the brakedrum G, its outer end being engaged with the outer surface of the pawl N, as shown at it.

Q is a rod or bar connecting the end of the pawl N with a lever, B, pivotally engaged with the frame, the construction being such that by operating said lever the pawl N may be disengaged with the ratchet-wheel and the brake applied. Then, by disengaging the pawl L, the movement of the sprocketwheel is entirely under the control of the brake, and thereby the stone may be lowered.

WVith this device very heavy weights can be lifted, when the truck upon which the frame is mounted may be wheeled off the field with the weight.

The operation of lifting and lowering the stones can be expeditiously performed.

WVhat I claim isl. The combination, with a truck, of a frame engaged therewith, said frame consisting of integral timbers bent upwardly intermediate of their ends and suitably braced, and

ICC

device connected with said sprocket-wheel, the, construction being such that when the ratchet-wheel is rotated in the proper direction power will be applied through the sprocket-wheel to the gripping device, substantially as described.

In testimony whereof I sign this speoifica- 20 .tion in the presence of two witnesses.
